Description
N Male to N Female Fixed Attenuator | 20 dB | 5 W | Screw-lock | Brass Body
The ROSNOL FA-N1N25A-6G5W20/133-93 is a precision-engineered fixed attenuator designed for RF and microwave signal control across DC to 6 GHz. This N-type attenuator provides a nominal attenuation of 20 dB with an attenuation deviation of ±0.7 dB, ensuring stable and repeatable attenuation performance. Rated for 5 watts average power at 25°C, it maintains a VSWR ≤1.20 for excellent return loss. The screw-lock coupling mechanism supports secure connections and reliable mechanical performance.Constructed with a brass body and beryllium copper center contact, this attenuator features gold plating over a nickel-phosphorus underlayer for enhanced conductivity and corrosion resistance. PTFE insulation offers excellent dielectric properties, while silicone rubber components ensure reliable sealing. Mechanical durability is further supported by robust coupling retention.
ROSNOL’s precision-engineered RF attenuators deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL attenuators offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
